      More Details Abstract Fulltext PDF

      Two ion sources of the charged particle oscillator type are described. The discharge chamber consists of an outer cylinder as cathode and an axial wire or a pair of wires along the axis as the anode. The energy spectra and ionic composition of the ion beam have been measured with a double focusing mass spectrometer of the Mattauch-Herzog design constructed in the laboratory. A high percentage of dissociated ions and multiply charged ions has been observed in the ion beam. A brief description of the mass spectrometer is also given.
